Making women feel more comfortable about marijuana is key to ending prohibition, according to Wendy Chapkis, a University of Southern Maine sociology professor. Women vote more than men, and the gap is growing among younger voters. amp;ldquo;While smoking may culturally be a guy thing, voting is increasingly a girl thing,amp;#8200;amp;rdquo; Chapkis wrote in an academic article titled amp;ldquo;The Trouble with Mary Janeamp;rsquo;s Gender.amp;rdquo; The more that women influence pot culture, the more they make other women at ease with it. That was crucial, according to Chapkis, to last yearamp;rsquo;s voter approved initiatives legalizing weed in Colorado and Washington.
